Math Problem Statement

I count on in equal steps. My first number is -2, my fifth number is 26. What is my third number?

Solution

In this problem, you're given a sequence where the first number is -2, and the fifth number is 26. The numbers increase by equal steps.

We can find the common difference (step) between each number. Let’s denote the numbers as:

  • First number: -2
  • Fifth number: 26

The difference between the first and fifth number is 26−(−2)=2826 - (-2) = 28.

Since there are four steps between the first and fifth numbers (1st
